This is Rama’s advice to Sugreeva on his coronation. Rama killed Sugreeva’s brother Vali and helped Sugreeva become king. On his coronation Rama advices him to follow the path of justice. One’s birth and death are direct results of one’s action (Karma) in this world. Even Brahma, the creator of humankind (who was born in a lotus) will face his end if he deviates from the righteous path. When Brahma the creator himself is bound by Karma, the human beings have no choice but to abide by the rules.
